Sewage farm

Sewage systems are for the purification of waste water.

The wastewater is the largest possible area irrigated on a well drained soil body. When drain into the ground, the ingredients are mechanically retained on the soil particles. The so- filtered substances are biodegraded by sessile (on ground grain grown ) microorganisms.

With the growth of urban settlements and the findings of hygiene, the demand for wastewater treatment was detected. The sewage farm technology in the 19th century, an early form of waste recovery and led to the emergence of the profession of Rieselwärters. Building on the research of Justus von Liebig on the material cycle it was propagated by social reformers such as Edwin Chadwick and George Varrentrapp. With his experience in England James Hobrecht designed an extensive drainage for Berlin, which was the third largest metropolis by the 1870s. This technique was also favored by the development of Hygiene Research by Robert Koch.

Wetlands are a related methodology to be clarified.

Today disused sewage farms have been in many places again converted or built in agricultural use. But if the irrigator continued and the water covering maintained, such as in Europe reserve sewage Münster, these areas offer numerous shorebirds and waterfowl habitat. While the sewage Münster offered more by pulling waders quarters in times of active Rohabwasserverrieselung, there are now mainly ducks birds ( which is much poorer in nutrients ) through the feed with now vorgeklärtem sewage here have become particularly numerous. Also amphibians are much more common today, they were once hardly to be found in the much more polluted water.

The former Freiburg sewage farm is now a district with the same name,.
